Abstract

Foam-backed mouldings are produced by placing a surface material in a foaming mould and then introducing the reactive foaming mix. A polymer is applied to the back of the surface material at certain areas before the mix is added; this polymer is thermoplastic or thermoset type, e.g. a polyurethane casting resin.
